Supply of Front End I17 for Diamond-II

Descriptions

Located on the Harwell Science & Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. DLS allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level.

To continue delivering the world-changing science that Diamond enables, the facility is being upgraded to Diamond-II, a co-ordinated programme of development that combines a major machine upgrade with new instruments and complementary improvements to optics,detectors, sample environment and delivery capabilities, and computing, as well as integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences.

The scope of the contract is to design, manufacture, supply, test and deliver one Front end for the I17 beamline in Diamond-II.

The term 'Front End' refers to the section of the synchrotron that runs between the stoage ring and the shield wall. The front end conditions the beam in preparation for use on the beamline.

The Front End will be located in a restricted area so it must be capable of continuous operation over long periods without maintenenance. The support frames must be rigid construction and constructed so that they minimise the effects of ground vibrations. The support frames must be supported from the floor with 3 manually adjustable feet to allow them to be accurately surveyed into position.

The Front End will be procured as a single turnkey unit, subject to the performance specification. The system comprises:

1. One complete Front End

2. All cabling, cable management features & connections to

junction boxes & bulkheads located on the Front Ends

3. One lifting frame

4. Bake out equipment

5. Sufficient spare parts to guarantee system operation with

minimum down-time for a period of at least two years from the

date of final acceptance.
